This input module is sensitive to electrostatic discharge. This module

is shipped in static-shielded packaging to guard against electrostatic

discharge damage. Observe the following precautions when handling

this module.

Electrostatic Discharge Damage

ATTENTION: Electrostatic discharge can damage

integrated circuits or semiconductors if you touch

backplane connector pins. Follow these guidelines

when you handle the module:

• Touch a grounded object to discharge static potential

• Wear an approved wrist-strap grounding device

• Do not touch the backplane connector or

connector pins

• Do not touch circuit components inside the module

• If available, use a static-safe work station

• When not in use, keep the module in its original

static-shielded packaging

DC (10-30V) Input Module ! Pre-installation Considerations ATTENTION: This module is equipped with a plastic cover that is unique to assembly numbers 960364-05 and 961344-01. (This part number is located near the backplane edge connector pins on the component-side of the circuit board.) Do not use this plastic cover on any other module. The 1771-IBD Series B module is compatible with all chassis except 1771-A1, 1771-A2, 1771-A4 chassis.

DC (10-30V) Input Module 3 Power Requirements Your module receives its power through the 1771 I/O chassis backplane from the chassis power supply. The module requires 130mA from the output of this supply. To calculate the requirements for the backplane power supply, add 130mA to the power requirements of all other modules in the I/O chassis. Calculating the requirements will prevent an overload to the chassis backplane and/or backplane power supply.

DC (10-30V) Input Module Install the Module and Field Wiring Arm ! ATTENTION: Remove power from the 1771 I/O chassis backplane and field wiring arm before removing or installing an I/O module. • Failure to remove power from the backplane or wiring arm could cause module damage, degradation of performance, or injury. • Failure to remove power from the backplane could cause injury or equipment damage due to possible unexpected operation.

DC (10-30V) Input Module Connect Wiring to the Field Wiring Arm 5 Make wiring connections to the field wiring arm (cat. no. 1771-WH) shipped with the module. 1. Connect one terminal of your two or three-wire input device to terminals 00 through 17. 2. Connect the +dc line to the other terminal of your input devices. Connect three-wire input devices, such as Allen-Bradley proximity switches (Bulletin 871), to operate in a current source mode. 3. Connect terminal E to the dc common.
